AIUTO DUMQI 'TR-UCK.

Applicationv filed. August 15, 1921.. Serial No. l1-93,201.

ville, in the county of Pittsylvania and State v of Virginia, have invented certain new and useful Improvements in Auto Dump Trucks, of which the following is a specification.

This invention relates towhat are known motor-driven dump truc-ks, in which provision is made for discharging the load from the container when the latter is moved to discharging position either behind the truck or to one side thereof,.and the object of the invention is to provide improved means for supporting the container and for shifting its position to equalize the weight of the load on the truck and to discharge the load on either Side of the truck or at the rear thereof.

In carrying out my invention I provide a motor driven truck on which is mounted a load supporting frame which is mounted on a turntable whereby the load supporting frame may be moved to a position either lengthwise of the truck or crosswise thereof. This frame supports a hopper bottom container which is movable longitudinally of the load supporting frame. Provision is made for turning the frame about the axis of the turntable and for moving the container longitudinally of its supporting frame.

My improvements are illustrated in the accompanying drawings, in which Figure l is a side elevation of an auto dump truck embodying my improvements.

Figure 2 is a plan view thereof.

Figure 3 is a transverse sectional View showing certain details of construction.

Figure 4 is a side elevation of the rear pol-tion of the truck, showing different positions of the load container.

Figure 5 shows a rear elevation of the truc-lr with the load container shifted to one side thereof.

The truck proper' may be of any suitable construction. Brieiiy stated, it comprises a chassis A supported on front and rear wheels B and C. An engine may be located at D and said engine may be connected in any suitable way with the rear wheels at E as indicated in Figure 5.

A load supporting frame F is supported on the chassis A by means of a turntable G so that the frame may be turned about the axis of the table to assume a position lengthwise of the truck or crosswise thereof. The

frame F lmay be made of channel iron` as shown, its slde members providing guides for the container whereby the latter may be Vmoved longitudinally ofthe frame.`

For turning the frame F horizontally about the axis of the turntable, I employ a winch H operated bya crank handle L and connected by ay rope, chain or cable J with the turntable. By these meansvthe frame may be turned from a position lengthwise of the truck to a position crosswise thereof as indicated in Figure 2.

The container K is preferably of the kind shown, having a hopper bottom closed by a gate L pivoted at its inner end to the container. When the container is located in the middle portion of the frame F, the gate L of the container is held closed by rails M supported in the frame F. The rear ends of the rails are turned downward as shown and support the gate when the latter is lowered. Braces m support the rear ends of the rails. Gate L of the container is adjustable to any angle.

In order to move the container longitudinally in the frame F, I employ a winch N operated by a handle n, and connected by a rope, chain or cable O with the bottom frame of the container as indicated at o. This rope, chain or cable extends to the rear end of the frame F and passes around a pulley o and is then connected with the container. By these devices the container may be moved longitudinally in its supporting frame. Cross pieces P serve to support the :rails M as indicated. The bottom frameI of the container K is provided with rollers k which travel in the channel irons forming the sides of the frame F.

By the mechanism shown the load con`4 fainer K may be moved to such a position on the truck. as to equalize or balance the weight of the load on the truck. This is an, impor tant feature of the invention. If it he desired to dump the load at the rear of the truck, the container is moved rearwards on the frame F until the gate L reaches the ends of the rails M when the gate will automatically drop, being sustained by the rear ends of the rails M as shown.-

If it be desired to dump the load at the side of the truck, the frame F is turned about the axis of the turntable as indicated in Figures 2, 4 and 5. When the container is moved to the extended end of the treme) the vgute is automatically lowered end the load is discharged.
